The Queen will today meet soldiers who have moved into the former RAF base at Leuchars.
On a visit to the Royal Scots Dragoon Guards, she will unveil a plaque naming the base Waterloo Barracks.
The army took control of the site in April and soldiers have gradually been moving there from their base in Germany.
The Queen will meet serving soldiers and their families before joining officers for a regimental photograph and a private lunch.
The new base will be fully manned by next summer when the Royal Scots Dragoon Guards return from operational training in Canada.
Military personnel and their families based there will number around 1,800, with soldiers also coming from the Royal Electrical and Mechanical Engineers (REME) and the Royal Military Police.
The Queen’s visit comes after the Duke of Edinburgh was at the base earlier this month visiting the REME in his role as its colonel-in-chief.
